This invention relates to door operated devicesl A of the atomizing orspraying type, and more especially to devices that are adapted foroperation by .the opening and closing movement of a door so as toperiodically introduce a .certain atomized liquid into a bathroom,clothes closet, or other room for one purposewor another.

One object of my invention is to provide a novel device of the typeindicated. I 1

Another object is to provide such a device l which has certainstructural and functional features of advantage over rthe similardevices of the prior art.

A further object is to provide such a device which includes areplaceable container as Well as means whereby the container can' bequickly and easily exchanged.

It is also anobject to provide such a device vwhich can be quickly andeasily adjusted for uniform operation.

l Another object is to provide such a device which can be quickly andeasily installed on any door frame for operation by the swingingmovement of the door.

A further object is to provide ,a novel door operated device of theindicated type which is simple and inexpensive in construction and canbe universally applied for various purposes.

With these and other objects in view,v which will become more readilyapparent from the fol- -lowing detailed description of the practical andillustrative embodiment of my device shown in the accompanying drawing,the invention comprises-the novel device, elements, features ofconstruction and arrangement of parts in coopera-- tive relationship, asmore particularly defined by thehereto appended claims. f

In the accompanying drawings: f Figure l is an elevational View of aportion of a door frame and door having my novel device cooperativelyapplied thereto. Fig 2 is a detail front elevational view of thek:device with the cover removed so as to disclose certain structuraldetails thereof.

Fig. 3 is a vertical sectional view taken sub-` stantially as indicatedby the arrows 3 3 in Figure l.

Fig. 4 is a vertical sectional view-taken substantially as indicated bythe arrows 4 4 in Figure 2.

Fig. 5 is an 'enlarged longitudinal sectional view taken substantiallyas indicated by the arrows 5`5 in Fig. 4.

It will be helpful to a clear understanding of my invention to i'lrstbriefly consider some of the more important -aspects and featuresthereof, so

A*that these may be .kept in mind during the sub- `sequent:reading ofthedetailed description ofthe practical and illustrative. embodimentof'my novel device disclosed in the accompanying drawing,

.2 claims. (cl. 2994825) i Accordingly,it is pointed out that theatomizing device may be-used for example, to ydeliver` a liquid sprayVor deodorant, or perfume, to-eliininate objectionable'odors in-rooms.Aor otherenclosures, or it may be' used todeliver allquid spray ofdisinfectant or insecticide to treat'the air in a closet so -thatmothsor other insect life cannot exist therein. y

The `construction of the devicev is such that the partsf thereof may beinconspicuously mounted on the "door and door'frameand arranged -in such-manner that the supply oflquid used inV the device can be readilyrenewed or exchanged.

1 'The liquid to be ejected by the device is preferably stored in a`gla'sscontainer of afcertain shape that will'fit into a casingdesignedto'also support Ithe spraying mechanism' in' a predeterminedposition so'thatthe device can be-eiiciently door operated in suchmanner that thesprayis accurately directed through Van opening-*inl thecasing and'eifectivelydirected lin-torthe room. v

Referring now more particularlyto thegures ofthe drawings Ain which likereference-characters indicateV like parts, the device comprisesarectangularly 'sh'apedrcasing IV which is Eadapted to be vfastened to adoor frame ,lV located above a door 3. Screws 4, which pass through-theback of the casing, are'used to rmly supportand permanently hold thecasing ini'tsproper posiiront and in thiscover is provided an opening 1through'which the spray is directed by the spraying'or atomizing'device,as Will presentlyappear.

AThe covert isalsofprovided with 'an-cpeninga which allows.the-foperating member Sfto .move

into and'out of the casing in itsmovement'by-the door'3 for theoperation of the spraying or atomizing *unit .of the device hereinaftermore particularly described. The cover 6 ,is adapted to'slide yinsuitable vvertical'-channels y formed i-njeach to permit access to theinside of -the'casing-for .of the spray supply.

the insertion of the spray unit or the replenishing The spray .unitcomprises a. spray head- Irlga liquid -tube l2 which leads into theside-ofthe 1 head, -a fixed coupling `I3 which-leads into the bottom ofthe head and carries at its lowerenda seal the head to the container.

The container I6 is preferably made of glass and is positioned asillustrated in Fig. 2 so that its outlet is located in the neck I'I atthe right hand agudfncar-the ,top thereof. Thevcontainer I6 ispre'ferably..,but:not necessarily, :rectangular in shape and has bevelededges at the bottom and rounded edges at the top. Its dimensions aresuch that it readily ts into the casing I behind fin-ietlaperture-Z-`and ya spray outlet lor 'nozzle 2 I 'Theinlet Aaperture 201s located'so -as to admit "airjinto the Ycontainer I6 through the neck I'I1thereof so asto keep the contents of thelconftainerunderconstantatmosphericpressure. The "spray-outlet or nozzle ZIis located inthe head substantially at the junctionlof `tlfierextensions ofetheliquid tube I2 -and the `air l"duct inthe jcouplingilli, While the`nozzle-21 is f-so `arranged lthat air 4forced VintoV -the 'head YI I,on the vcompression of VV:the -bulb` I4, lwill be vforced through theoutlet or nozzle 2 I tofcreate a'partial vacuum 'ini-the head-that-willcausethe atmospheric 1 pres- I-sure to force someof :'theliquid fromAthe con- -ftainer through thetube'iZ into-the Vhead ,so aas4"to:mi-xnyvith thefair from thebulb and be forced fromithe nozzleintheViormof anspray.

A'alsiillus'trated'in Fig. 3, thebulb I 4 'is compressed, :as:illustrated fin section `in this iigure. -However, as soon 4as the dooris :opened, Athe operating l:member '5 =is withdrawn Strom in iront .ofthe and @forces out or the nozzles l.

While I have shown .and ,described the .spray head IrI as being ofxaparticular construction, it 'iis pointed out that-this construction isstandard 'and maybe purchased on :the open marketexcept Vfor'therotating coupling VIii associated therewith which provides for -the:adjustable*fastening .of

thus bereadily madeand the `head adjusted so that its nozzle 2i will bein line with the discharge opening 'l in the cover of the casing.

As illustrated in Fig. l, the spray device is preferably installed asuitable distance from the hinged side of the door in order to providethe proper movement for the operating member 5 finitscompression of thebulb I4 on the closing of the door. The openings 6a and 22 are enlargedto permit an unobstructed arcuate movement of the operating member as itmoves in and cut of Vthe casing I by the swinging move- -ment ofthedoor. .Suitable bolts123-,23 are used shapedcasmg, a removable coveratthe frontof said casing having two predeterminately'located openingstherethrough, an interchangeable conitainer correspondinglyreotangularly shaped to y,said casing so as to be predeterminately heldnested at one end of said casing, .a neck project- Ving from 4one endsubstantially at the top of said container, ,a Yspray head `including a:nozzlesuspended from said neck and rotatably :adjustable thereon to,bringgsaidnozzle in alignment with one soi the openings in-said cover,a compressible bulb .suspended from `said spray head for operationthereof, and an operating member carried by the door ,for movementthrough the other `of said openings ,in said vcover into said teasingfor engagement and compression of said bulb during closing movement of-said door.
